## Description

Pingtunnel is a network utility that implements ICMP tunneling by encapsulating TCP and UDP traffic within ICMP echo packets. It functions as an encrypted network tunnel and a SOCKS5 proxy server, allowing network traffic to be routed through a secure channel to bypass restrictive firewalls and network filters.

The tool secures transmitted data using symmetric encryption to prevent interception of the tunneled payload. It uses a SOCKS5 proxy interface to accept standard network requests and redirect them into the ICMP tunnel.

The system includes adaptive network polling to balance latency and CPU usage, and it utilizes protocol buffer serialization for control messages.

The application is provided as a containerized network utility to simplify installation and dependency management.
